Wolf, a world covered in red vegetation and shallow seas. Classified as a superhabitable world with an average temperature of 25 Celsius and measuring 1.31 Earth radii and 1.99 Earth masses. Orbits a K-type star about 2 billion years older than Sol.

This looks fun!

Have you thought about creating planets inspired by us?

I imagine I'd be a pink gas giant with a chaotic rotation.

Rust, a planet astonishingly similar to Mars geographically, measuring 0.61 Earth radii and 0.15 Earth masses. Its surface even has a thin coating of iron oxide just like Mars. But there is one crucial difference: it is only 2 billion years old and still has oceans teaming with single-celled life. Already this world is slowly losing its atmosphere to the relentless solar wind. Another billion years and, without human intervention, its atmosphere will be reduced to an insubstantial state and its oceans will dry up. For now, though, colonists can live here with only oxygen masks. In a way, this world is a window to Mars's distant past.

The cold Super-Earth Shickshinny, measuring 1.24 Earth masses and 1.57 Earth radii, with an average surface temperature of -42 Celsius. This shows the planet as it appeared before the terraforming began. The planet can be divided into fairly clearly delineated highland and lowland regions, with the highlands averaging 3 kilometers above the lowlands and being significantly lighter in color.

In time, Shickshinny was terraformed. Comets were smashed into its surface, their water covering the dark lowlands and releasing useful greenhouse gases into the atmosphere. But funding dried up before the next phase could begin, and so it remains half-terraformed, with seas and a breatheable atmosphere, but no vibrant forests and grasslands.

Janus, a super-Earth with no substantial axial tilt. Yet it still has seasons due to its high eccentricity--an "orbital summer" and "orbital winter" as it orbits between 0.86 and 1.44 AU around its sunlike star. The planet is 0.98 Earth radii and 1.06 Earth masses. Here is Janus at the beginning of the orbital winter, before the oceans have had time to freeze over:

Posi, a large water world--almost a gas dwarf--measuring 2.7 Earth radii and 10.3 Earth masses. The 50-60 Celsius waters and the lack of land allow colossal hypercanes the size of Mars with 1000-kilometer-per-hour winds to rage across the surface of the planet, lasting for years without dissipating. Here we see the planet during a rare quiet period without hypercanes over an entire hemisphere, which happens once every few centuries.

Could you have a world that is so unbalanced? Wouldn't it be weirdly top heavy, or the extra weight might mess with it's rotation, although I guess 0 axial tilt might make that a non issue?

 

(I mean of course you could​ have a planet like that, but would It need special conditions to form or is the difference in crust thickness between the continent and ocean small enough that on a planetary scale its only a minor thing?)

I mean, Earth has had all its land on one side at one point or another.

Ratho is a cold world measuring 1.45 Earth radii and 2.57 Earth masses. It orbits the K-type star Tarr 227 light years from Sol, in the coreward part of the Izar Volume. Prior to its colonization in the 6th century* of our lord EloN, complex life had yet to develop on land, thin algae-like films had colonized the coastlines. However, once colonists from solward had arrived in their gardenships, development was quick, but not quick enough to make the nightside glow brightly with city lights as in so many of the core worlds. In 600*, there are more than a million residents in the orbitals, and two million on the surface. Most of these reside in the domed complexes on Drakum Island (the large island in the northern hemisphere, near the terminator line). However, about 100,000 have abandoned this area over political disputes and migrated west and south to the Michelangelo Peninsula, where they live in airtight, radiation-shielded tents like the Proxis of old.

Winter, a cold world measuring 0.98 Earth radii and 1.05 Earth masses. This one, unlike so many others, has continuous, deep oceans with most of the land in large continental landmasses. That said, the surface is more than 80% water, with most land consisting of mountainous evergreen forests in the equatorial latitudes. Meanwhile, the seas are dominated by extensive ice sheets.
